Posting on behalf of DH, who is very worried. Here's what he's written. Any advice, insights or similar experiences appreciated!
My father is 81 years old, lives by himself, and has limited mobility due to a leg ulcer. He has had the ulcer for 8 years or more, and it dominates his life. His days are a cycle of dressing changes, medication, and keeping himself occupied as best he can in his bungalow. He has become pretty frail and under-nourished, though I’m hoping the latter will be addressed with a new meals service he has found.
He has previously been a keen driver, and it’s actually pretty difficult to live where he does (in a tiny village in Devon) without his own transport. Following a fall which made him more unsteady on his feet, he hasn’t been driving for several months now. Even when he was driving, he had one serious accident (no serious injuries, fortunately) and several smaller prangs. He claims all of these accidents have been other drivers’ fault – I struggle to believe this but can’t prove otherwise.
He has been saying for some time that he’d like to get back to driving. He even claims that he has had someone assess his driving in a ‘test’ of some sort, but again I don’t really believe this (and no evidence has been forthcoming). I’ve suggested he sell his car and use the funds to pay for taxi trips when needed, but he’s not keen.
He is also displaying some issues with his short-term memory, which I’d previously assumed were a side-effect of the medication, but increasingly think they may be indicators of some sort of dementia.
In short, I don’t want him to drive again. I have little chance of ‘persuading’ him to give up, and I don’t want to go down the route of secretly informing DVLA unless I really have to. What I’d like is some advice on whether he should be driving at all, based on the medication he is taking.
Currently, he is taking slow release morphine twice a day – 30mg morning and evening. When he has significant pain, he tops this up with up to 30ml of liquid morphine, possibly more. (My sister is concerned that his GP isn’t following the recommendation that if morphine doesn’t stop the pain, it shouldn’t be prescribed. But this is a separate issue.)
My question is whether someone is likely to be able to drive safely on this kind of morphine dose – either on the regular slow release dose or the increased dose. I’m pretty sure he wouldn’t drive when feeling a lot of pain anyway, but I suspect that he shouldn’t be driving even on the smaller dose. The law allows for people prescribed morphine to drive (up to 80µg/L in the blood), but I don’t know in practice how my dad’s dosage translates to blood levels.
I’m aware that there are bigger issues here – whether he should be living alone, the possibility of dementia tests, whether this too impacts his ability to drive. But it struck me that the morphine question may be the quickest and easiest one to answer for now.
Many thanks for any help/advice you can offer
